Fixes #116473

The span computation was wrong. It went from the end of the variant to the end of the (wrongly placed) args. However, the variant lived in a different expansion and this resulted in a nonsensical span that overlaps with another and thereby leads to the ICE.

In the fix I've changed span computation to not be based on the location of the variant, but purely on the location of the args. I simply extend the start of the args span 2 positions to the left and that includes the :: and that's all we need apparently.

This approach produces a correct span regardless of which macro/expansion the args reside in and where the variant is.

…ants

When the variant and the (wrongly placed) args are at separate
source locations such as being in different macos or one in a macro and
the other somwhere outside of it, the arg spans we computed spanned
the entire distance between such locations and were hence invalid.

    Auto merge of #116497 - compiler-errors:impl-span, r=cjgillot

    Extend `impl`'s `def_span` to include its where clauses

    Typically, we highlight the def-span of an impl in a diagnostic due to either:
    1. coherence error
    2. trait evaluation cycle
    3. invalid implementation of built-in trait

    I find that an impl's where clauses are very often required to understanding why these errors come about, which is unfortunate since where clauses may be located on different lines and don't show up in the error. This PR expands the def-span of impls to include these where clauses.

    r? cjgillot since you've touched this code a while back to make some spans shorter, but you can also reassign to wg-diagnostics or compiler if you're busy or have no strong opinions.

    Auto merge of #116142 - GuillaumeGomez:enum-variant-display, r=fmease

    [rustdoc] Show enum discrimant if it is a C-like variant

    Fixes https://github.com/rust-lang/rust/issues/101337.

    We currently display values for associated constant items in traits:

    ![image](https://github.com/rust-lang/rust/assets/3050060/03e566ec-c670-47b4-8ca2-b982baa7a0f4)

    And we also display constant values like [here](file:///home/imperio/rust/rust/build/x86_64-unknown-linux-gnu/doc/std/f32/consts/constant.E.html).

    I think that for coherency, we should display values of C-like enum variants.

    With this change, it looks like this:

    ![image](https://github.com/rust-lang/rust/assets/3050060/b53fbbe0-bdb1-4289-8537-f2dd4988e9ac)

    As for the display of the constant value itself, I used what we already have to keep coherency.

    We display the C-like variants value in the following scenario:
     1. It is a C-like variant with a value set => all the time
     2. It is a C-like variant without a value set: All other variants are C-like variants and at least one them has its value set.

    Here is the result in code:

    ```rust
    // Ax and Bx value will be displayed.
    enum A {
        Ax = 12,
        Bx,
    }

    // Ax and Bx value will not be displayed
    enum B {
        Ax,
        Bx,
    }

    // Bx value will not be displayed
    enum C {
        Ax(u32),
        Bx,
    }

    // Bx value will not be displayed, Cx value will be displayed.
    #[repr(u32)]
    enum D {
        Ax(u32),
        Bx,
        Cx = 12,
    }
    ```

    Fix suggestion span involving wrongly placed generic arg on enum variants

    When the variant and the (wrongly placed) args are at separate
    source locations such as being in different macos or one in a macro and
    the other somwhere outside of it, the arg spans we computed spanned
    the entire distance between such locations and were hence invalid.

    This is a version of #106852 that does not check the current crate's debuginfo flag, and always attempts to preserve debuginfo.

    I haven't figured out how to handle mixing debuginfo levels for std, the one for the test, and the one for the CI target just right to merge #106852, so this can at least fix the debuginfo issue.

    Fix to register analysis passes with -Zllvm-plugins at link-time

    This PR fixes an unexpected behavior of the `-Zllvm-plugins` flag. It allows to run an out-of-tree pass as part of LTO.
    However, analysis passes are registered before the plugin is loaded. As a result an analysis pass, which is passed as a plugin, is not registered. This causes the LLVM PassManager to fail when the analysis pass is queried from a transformation pass  [(here)](https://github.com/llvm/llvm-project/blob/main/llvm/include/llvm/IR/PassManager.h#L776).

    This fix mimics the bahavior in [LLVM LTOBackend.cpp](https://github.com/llvm/llvm-project/blob/main/llvm/lib/LTO/LTOBackend.cpp#L273) by loading the plugin before the analysis passes are registered.

    Tested with rustc 1.60 and 1.65 and LLVM-13.0.1.

    Auto merge of #100806 - timvermeulen:split_inclusive_double_ended_bound, r=dtolnay

    Fix generic bound of `str::SplitInclusive`'s `DoubleEndedIterator` impl

    `str::SplitInclusive`'s `DoubleEndedIterator` implementation currently uses a `ReverseSearcher` bound for the corresponding searcher. A `DoubleEndedSearcher` bound should have been used instead.

    `DoubleEndedIterator` requires that repeated `next_back` calls produce the same items as repeated `next` calls, in opposite order. `ReverseSearcher` lets you search starting from the back of a string, but it makes no guarantees about how its matches correspond to the matches found by a forward search. `DoubleEndedSearcher` is a subtrait of `ReverseSearcher` and does require that the same matches are found in both directions.

    This bug fix is a breaking change. Calling `next_back` on `"a+++b".split_inclusive("++")` is currently accepted with repeated calls producing `"b"` and `"a+++"`, while forward iteration yields `"a++"` and `"+b"`. Also see https://github.com/rust-lang/rust/issues/100756#issuecomment-1221307166 for more details.

    I believe that this is the only iterator that uses this bound incorrectly — other related iterators such as `str::Split` do have a `DoubleEndedSearcher` bound for their `DoubleEndedIterator` implementation. And `slice::SplitInclusive` doesn't face this problem at all because it doesn't use patterns, only a predicate.

    Rollup merge of #116458 - bjorn3:fix_global_asm_test, r=workingjubilee

    Properly export function defined in test which uses global_asm!()

    Currently the test passes with the LLVM backend as the codegen unit partitioning logic happens to place both the global_asm!() and the function which calls the function defined by the global_asm!() in the same CGU. With the Cranelift backend it breaks however as it will place all assembly in separate codegen units to be passed to an external linker.

    Reuse existing `Some`s in `Option::(x)or`

    LLVM still has trouble re-using discriminants sometimes when rebuilding a two-variant enum, so when we have the correct variant already built, just use it.

    That's shorter in the Rust code, as well as simpler in MIR and the optimized LLVM, so might as well: <https://rust.godbolt.org/z/KhdE8eToW>

    Improve `redundant_locals` help message

    Fixes #11625

    AFAIK, `span_lint_and_help` points the beginning of spans when we pass multiple spans to the second argument, so This PR I also modified its help span and its message.

    lint result of the given example in the issue will be:

    ```console
    error: redundant redefinition of a binding `apple`
     --> src/main.rs:5:5
      |

    Auto merge of #3067 - Vanille-N:spurious-incremental, r=RalfJung

    Continuation of #3054: enable spurious reads in TB

    The last additions to the test suite of TB left some unresolved `#[should_panic]` that these new modifications solve.

    ## Problem

    Recall that the issues were arising from the interleavings that follow.

    ### A. `Reserved -> Frozen` has visible effects after function exit

    The transition `Reserved -> Frozen` irreversibly blocks write accesses to the tag, so in the interleaving below `y` initially `Reserved` becomes `Frozen` only in the target where a spurious read through `x` is inserted. This makes the later write through `y` UB only in the target and not in the source.
    ```
    1: retag x (&, protect)
    2: retag y (&mut, protect)
    1: spurious read x
    1: ret x
    2: ret y
    2: write y
    ```

    ### B. Protectors only announce their presence on retag

    There is a read-on-reborrow for protected locations, but if the retag of `x` occurs before that of `y` and there is no explicit access through `x`, then `y` is unaware of the existence of `x`. This is problematic because a spurious read inserted through `x` between the retag of `y` and the return of the function protecting `x` is a noalias violation in the target without UB in the source.
    ```
    1: retag x (&, protect)
    2: retag y (&mut, protect)
    1: spurious read x
    1: ret x
    2: write y
    2: ret y
    ```

    ## Step 1: Finer behavior for `Reserved`

    Since one problem is that `Reserved -> Frozen` has consequences beyond function exit, we decide to remove this transition entirely. To replace it we introduce a new subtype of `Reserved` with the extra boolean `aliased` set.
    `Reserved { aliased: true }` forbids child accesses, but only temporarily: it has no effect on activation once the tag is no longer protected.
    This makes the semantics of Tree Borrows slightly weaker in favor of being more similar to noalias.

    This solves interleaving **A.**, but **B.** is still a problem and the exhaustive tests do not pass yet.

    ## Step 2: Read on function exit

    Protected tags issue a "reminder" that they are protected until this instant inclusive, in the form of an implicit read (symmetrically to the implicit read on retag). This ensures that if the periods on which two tags `x` and `y` are protected overlap then no matter the interleaving of retags and returns, there is either a protector currently active or a read that has been emitted, both of which temporarily block activation.

    This makes the exhaustive test designed previously pass, but it has an effect on the ability to return an activated pointer that I had not foreseen before implementing it.

    ## Step 2': Do not propagate to children

    A naive implementation of **Step 2** makes the following code UB:
    ```rs
    fn reborrow(x: &mut u8) -> &mut u8 {
        let y = &mut *x;
        *y = *y;
        y // callee returns `y: Active`...
    }

    let x = &mut 0u8;
    let y = reborrow(x); // ... and caller receives `y: Frozen`
    *y = 1; // UB
    ```
    This is unacceptable, and a simple fix is to make this implicit read visible only to foreign tags.

    We still lack hindsight on the ramifications of this decision, and the fact that the problematic pattern was only discovered because it occured in one completely unrelated test (with a cryptic error message) is worrying. We should be vigilant as to how this interacts with the rest of the model.

    ## TODO

    As of commit #281c30, the data race model has not been fully updated.
    We have removed the reborrow of mutable references counting as a write access, but we still need the implicit read of function exit to count as a read.

    This just moves the main logic of the previous `dlsym` handler into an eval context extension so it can be used via both call paths. The `dlsym` handler is still needed as `getrandom` uses it.

    Rollup merge of #116421 - Urgau:inter-mut-invalid_ref_casting, r=oli-obk

    Clarify `invalid_reference_casting` lint around interior mutable types

    This is PR intends to clarify the `invalid_reference_casting` lint around interior mutable types by adding a note for them saying that they should go through `UnsafeCell::get`.

    So for this code:
    ```rust
    let cell = &std::cell::UnsafeCell::new(0);
    let _num = &mut *(cell as *const _ as *mut i32);
    ```

    the following note will be added to the lint output:

    ```diff
     error: casting `&T` to `&mut T` is undefined behavior, even if the reference is unused,  consider instead using an `UnsafeCell`
       --> $DIR/reference_casting.rs:68:16
        |
     LL |     let _num = &mut *(cell as *const _ as *mut i32);
        |                ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
        |
        = note: for more information, visit <https://doc.rust-lang.org/book/ch15-05-interior-mutability.html>
    +   = note: even for types with interior mutability, the only legal way to obtain a mutable pointer from a shared reference is through `UnsafeCell::get`
    ```

    Suggestion are welcome around the note contents.

    Factor out `insert_or_error`.

    It appears identically as a closure in two functions.

    Also change its return type from `bool` to `Option<()>` so it can be
    used with `?`.
